Rare Earth Coordination Polymers with Zeolite Topology Constructed from 4-Connected Building Units

A series of rare earth coordination polymers, M(BTC)(DMF)(DMSO) (M = Tb (1), Ho (2), Er (3), Yb (4), Y(5)), with zeolite ABW topology have been synthesized under mild conditions. They exhibit the same three-dimensional (3D) architecture and crystallize in monoclinic symmetry space group P21/n. Their structures are built up from inorganic and organic 4-connected building units, whose vertex symbols are 4·4·6·6·6·8. The building units link to each other to generate approximate 5 × 8 Å2 channels along the [100] direction. The luminescent and magnetic properties of these compounds are investigated, and the results reveal that they could be anticipated to be potential antiferromagnetic and fluorescent materials.
